A network time server is a device that provides a computer network with an accurate source of time. Accurate time is generally obtained from an external hardware clock reference, such as GPS or radio time and frequency broadcasts. Precise time is then maintained internally by a calibrated system clock. Servers, workstations and other network devices […]
Network Time Servers
Network Time Server and GPS NTP Appliances
With the expansion of distributed computer systems, network time synchronization has increasingly become of critical importance. A network time server provides computer networks with an accurate time resource. By utilizing GPS and radio time and frequency broadcasts it can provide highly precise timing information to client computers. Most time servers utilize the Network Time Protocol […]
NTP Network Time Server FAQ
Why Do I Need A Network Time Server? Computers have notoriously inaccurate clocks. They often use cheap, inferior, crystals and clock components. After a relatively short period of time, the clocks of two or more computers will significantly differ. For transaction processing, trading, data logging, and many other applications a consistent network time is imperative […]
Installing a T-Series GPS\GNSS NTP Server
Locating the Appliance TimeTools T-Series NTP server appliances should only be installed indoors. Locate the device in a rack, on a shelf, or in a cupboard. It should not be supported by the attached cables. Antenna Positioning Ideally, a GPS\GNSS antenna should be positioned in a location where the top of the antenna has a […]
NTP Hardware Reference Clocks: GPS, Multi-GNSS or Radio ?
There are a number of sources of accurate time available to timing applications. They divide into satellite navigation systems and national time and frequency radio broadcasts. TimeTools T-Series NTP servers use either GPS or Multi-GNSS timing references. Below is a list the associated advantages and disadvantages of each. GPS (Global Positioning System) GPS (Global Positioning […]
Secure NTP Server
The Network Time Protocol (NTP) is an Internet protocol built to distribute precise time around a computer network. NTP makes use of UDP over TCP/IP to synchronize network time clients to a precise time reference. This informative article talks about the security and safety elements of the NTP protocol and particularly making use of MD5 […]
